IMPROVEMENT IN WINDMILLS.

Specification forming part of Letters Patent No. 179,109, dated June 27, 1876; application tiled March 13, 1876.

To all whom it may concern:

Be it known that I, DANIEL HALLADAY,-of Batavia, in the county of Kane and State of Illinois, have invented a new and usetul Improvement in Windmills, which is fully set forth in the following specification, reference being had to the accompanying drawings, in whichy Figure lis a side elevation ofa mill with the wind-wheel removed and the lower part ot' the tower brokenaway. Fig. 2 is a similar view, showing the relative position ot' the parts when the wheel is turned out of the wind. Fig. 3 is a sectional view of the turn-table, taken on the line xx in Fig. l; and Fig. 4 is a bottom view of the tubular portion of the turntable.

My invention relates to mechanism for regulating the wheel, which is automatic in its `action in turning the wheel out of and into the wind.

My invention consists in pivoting the vane to the turn-table at an angle to the driveshaft, so that the wheel is gradually turned out by any increased force of the wind, and when so turned out of the wind the weight of the vane acts to turn it into the wind again, and also in various devices, which will be hereinafter more fully described.

In the drawings, A represents the supporting-frame or tower. B B are plates, upon which the turn-table C is mounted. The turntable consists of two parts-an upper plate, which rests upon the plate B, and a tubular portion, which extends downward andis journaled upon the plate B. Between the upper plate of the turn-table and the plate B is placed a ring of peculiar construction, carrying two sets of anti-friction rollers. This device is fully described and claimed in another patent, however, and further description is not necessary here. Upon the upper portion of the turn-table the main driving-shaft D is mounted, to the outer end of which the windwheel is attached. The vane E is pivoted to a yoke, F, which, in turn, is pivoted to the turn-table, and to alug upon a post, G, which is attached to the rear end of the turn-table. A rod, E', is hinged to the upper end ofthe post Gr, and to the vane E, in rear ot' its connection with the yoke F; and as the post G is at one y wheel will be at one side of the vane.

side of the vane, the point of attachment of the rod to said post is eccentric to the pivotal bearings of the yoke F. A yoke, I, is pivoted to one side ot'the forward end of the vane, in front of its attachment to the yoke F, and to this yoke I a pin, K, is journaled. An anguiar lever, L, is pivoted at its angle tothe upper end of the pin K, and the outer end ot' one of its arms is pivoted to the post G, the

arm being slotted, to admit of its sliding upon its pivotal pin M. A rod, N, is attached to the outer endet' the other arm of the angular lever, and extends down through t-he tubular portion of the turn-table, and is attached at its lower end to a slide, a, which is placed upon the connecting-rod b. g This slide is constructed with a groove, @extending around it, and is grasped by a forked piece, d, the arms ot' which enter the groove in the slide. A rod, e, is passed through the outer eudsot' these arms, and is extended in both directions, so that its ends will rest against two opposite posts of the supporting-frame, and prevent the forked piece from turning with the slide co. A short rod, f, depends from the other end ot' the forked piece d, to the lower end of which a cord or wire is attached, by means o't' which the angular lever is made to act upon the vane, to turn the wheel out of the wind.

In the lower end ot' the tubular portion of the turn-table a guide, g, is fixed. The connecting-rod b passes through a hole in the center ot' this guide, and grooves h are made in its side, to permit any water that enters the tubular portion ot the turn-table to liow out, and a smaller groove, z', is provided for the passage of t-he lever-rod N. A ring, 7c, is attached to the projecting lower end ot' the guide by means of a set-screw, l, which serves to hold the turn-table down in position, being larger than the opening in the supportingplate B which forms the bearing for the lower end of the turn-table.

The pivot'cd connection between the vane E and the turn-table is directly iu line with the axis of the drive-shaft; but the vane itself is arranged out of such line by turning it slightly away from the post G, so that the axis of the Vane will form an angle with the axis ot` the drive-shaft, and the greater portion ot' the There is a stop, m, on the post G, which is adjustable thereon by means of a slot, so as to regulate the position of the' vane by settingwit more or less awa-y from the post, according as the stop is moved back and forth thereon.

The operation is as follows: The vane being arranged as described with reference to the windwheel, the force of the wind Will have a tendency to turn the wheel still 'fartheraround toward the vane, and therefore, as the force of the wind increases, the wheel will be turned more and more out of the wind, until it is-tinally thrown entirely out of action, if the wind is sufficiently strong. The turning around of the wheel, described above, causes the outer end of the vane to rise as the post Gr is carried away from it, by reason of the strain brought upon the rod H, which is hinged to the post and vane. The weight of the vane, therefore, will constantly operate to carry it back toward the post, and thus bring the wheel back into the wind again, and retain it in this position It Will be seen, therefore, that the apparatus will be self-regulating. Whenever it is desired to turn the wheel out of the wind and stop it, it may be accomplished by pulling down the slide a, which depresses the outer end of the free arm of the angular lever L, and thereby applies 'force to the forward end of th`e vane, which will tend to throw this end around toward the post Gr; but as the vane is held in position by the Wind, the actual effect will be to rotate the turn-table, and thereby turn the Wheel out ofthe wind, the `swiveling connection between the lever and the vane and the slotted lever-arm permitting this movement. The wheel may be held in this position by fastening down the slide a by means of the cord or wire attached to it; but Whenever it is released, the wheel will be automatically turned back into the wind, as described above.

The forked piece d distributes the force actinn,` upon the slide a, so that when it is pulled down there is no binding upon the connecting-rod, and the cross bar e prevents this forked piece from turning around, and thus twisting the cordabout the connectingrod.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of a'turn-table, having a wind-wheel mounted thereon, a vane attached to the turntable by a swiveling joint, and mechanism which raises the outer end of the 'vanewhen the wheel is turned out of the wind,

so that the Weight of the Vane will operate to bring the wheel into the Wind again, subst-antially as described.

2. The combination of the vaneE, pivoted to the turn-table, the post G, and the rod H, substantially as described.

3. The `combination of the turn-table and the vane E, attached thereto by a swivel-cone nection, to admit of the horizontal movement of the turntable, and the raising of the outer end of the vane, substantially as described.

4. The combination of the vane E, the yoke F, and post G, the vane being pivotedto the yoke and the turntable, substantially as shown and described.

5. The combination ofthe vane E and angular lever L, attached to the forward end of the vane by a s wiveling connection, and to the post G- by a sliding connection, substantially as described.

6. The combination of the angular lever L, the pin K, Vand yoke I, pivoted to the forward end of the vane, substantially as described.

7. The guide g, grooved as described, and inserted in the, tubular portion ot' the turn-ta ble, as and for the purposes specified.

8. The combination of the guide g, the ring 7c, set-screw Z, and the tubular portion of the turn-table, substantially as described.

9. The combination of grooved slide a, con- 11ecting-roclb,the forked piece d, and extended cross-bar e, substantially as and for the purposes described.

l0. The combination of a Wind-wheel and vane, the latter arranged out ot' line with the drive-shaft, but hinged to the turn-table by a pivot in line with the axis of said shaft, so as to make the wheel self-regulating.

11. The combination of the hinged vane E and adjustable stop m, substantially as described.
